ATTACHMENT FOR CLEANING RODS Specification of Letters Patent.

Application filed June 20, 1914.

Patented Aug. 18, 1914.

Serial No. 846,251. r

To all whom it may concern:

Be it known that I, CARL P. MICKELSON, a citizen of the United States of America, residing at Mason, in the county of Ingham and State of Michigan, have invented certain new and useful Improvements in Attachments for Cleaning-Rods, of which the following is a specification, reference being had therein. to the accompanying drawings.

This invention relates to attachments for cleaning rods used for swabbing or cleaning the bore of a gun barrel, fire arm or piece of ordnance.

The primary object of my invention 13 to provide a combined swab and lubricant res ervoir that can be easily attached to the end of a rod, whereby the bore of a gun barrel can be thoroughly cleaned and oiled.

A further object of this invention is to provide a simple, durable and inexpensive device of the above type wherein effective means is employed for controlling the supply of lubricant to a swab or yieldable cleaner head.

The above and other objects are attained by a mechanical construction that will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, wherein- Figure 1 a side elevation of the device as connected to a portion of a cleaning rod; Fig. 2 is a longitudinal sectional view of the device, and F 3 a cross sectional view of the same.

In the drawing, 1 denotes a tubular or hollow cylindrical lubricant reservoir having the inner end thereof open and intoriorlv serewthreaded, as at 2, to receive a couplingmember and closure 3, said mem ber having a peripheral flange 4 that engages the end of the reservoir and limits the inward movement of the coupling member. The inner end of the coupling member terminates in an exteriorly screwthreaded shank 5 and a peripheral flange 6, said shank permitting; of the cm'lpling member being connected to a sectional or solid cleaning rod 7. The flange 6 limits the movement of the shank 5 in the cleaning rod and said flange is knurled or otherwise roughened, as shown in Fig. 1. to facilitate connecting the coupling member to the cleaning rod. By removing the coupling member from the open end of the reservoir 1, said reservoir can be readily filled with oil or a suitable lubricant. The outer end of the reservoir 1 is closed and terminates in a cylindrical boss 8 having a concentric exteriorly screw-threaded stem 9. The boss 8 is of less diameter than the body of the device and. said boss and the stem 9 thereof has a longitudinal bore 10. The boss alone is provided with a plurality of ports 11. establishing communication between the interior of the reservoir and the outer end of the boss.

Surrounding the boss 8 is a swabin the form of an annulus or washer 12 made of felt or a emnpressible and expansible ma terial that is also capable of absorbing and holding in suspension the lubricant or contents of the reservoir. Interposed between the boss 8 and the swab 12 is an oxpansible member 13, preferably in the form of a spring of one convolution, said member being held under compression by the swab and constantly exerting a pressure against the swab which maintains the same in spaced relation to the walls of the boss. Smrewed upon the stem 9 is a knurled cap 1 1? which retains the swab against the closed end of the reservoir. The cap 14 can be adjusted to completely close the ports 11 and thereby prevent the contents of the reservoir from passing through the ports onto the s 'ab or said cap can be adjusted whereby quantities of the lubricant can pass out of the ports and be absorbed by the swab. The swab .12 is made or": a sufficient depth to be partially compressed in its longitudinal dimension by the cap 14 and after each swabbing operation, the cap 14 can be adjusted to allow lubricant to escape from the reservoir and sulliciently saturate the swab.

One embodiment of my invention has been illustrated, but it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims.

\Vhat I claim is:

l. A device of the type described comprising a tubular reservoir. a coupling member carried by one end thereof, a boss carried by the opposite end of said reservoir, a swab encircling said boss, :1 tap detachably supported by said boss and engaging said swab, and a spring interposed. between said boss and said swab and adapted to expand said swab.

2. The combination with a cleaning rod, of a coupling member attached thereto, a tubular reservoir carried by said member, a

portedboss forming part of the outer end of said reservoir, an expansible swab surrounding said boss and adapted to receive the contents of said reservoir, and, means supported by said boss for controlling the supply to said swab.

3. The combination with a cleaning rod, of a tubular reservoir adapted to contain a lubricant, a ported boss carried by the outer end of said reservoir, an expansible swab surrounding said boss against the end of said reservoir,,a cap screwed upon a portion of said boss and adapted to control the sup ply of lubricant to said swab, and means at the inner end of said reservoir to facilitate coupling said reservoir to said rod.

4. The combination with a cleaning rod,

of a tubular reservoir, a coupling member closingone end of said reservoir and adapted to connect said reservoir to said rod, a ported boss closing the opposite end of said reservoir, a swab encircling said boss against the end of said reservoir, a cap detachably supported by a portion of said boss and adapted to retain said swab in position, and means interposed between said boss and said swab for normally retaining said swab expanded.

In testimony whereof I aflix my signature in presence of two witnesses.
